Additionally, it shows a brief history of cooperative development on Polish lands and statistical data on agriculture and cooperatives. Most attention is given to dairy cooperatives, cooperative groups of agricultural producers and agricultural production cooperatives. These types of cooperatives are the most popular in Polish agriculture. The fundamental law regulating the issue of cooperatives in Poland is the Cooperative Law Act of September 16, 1982. Other laws, however, also have a big influence on the business activity of agricultural cooperatives, especially the EU legal regulations. Poland membership in the European Union has created new possibilities of development for the cooperative movement.展开更多

Paramo environments provide important species habitat and ecosystem services. Changes in spatial extent of the paramo ecosystem at Pambamarca in the Central Cordillera of the northern Ecuadorian Andes were analysed using multi-temporal Landsat TM/ETM＋ satellite data. The region suffered a loss of 1826.6 ha or 20% of the total area at a rate of 100 ha/annum during 1988-2007 period. It is found that permanent paramo cover decreased from 8350 ha in 1988 to 5864 ha in 2007 at a fairly constant rate （R^2=0.94）. This loss is attributed to expansion of commercial agriculture and floriculture in the valleys coupled with increased population pressure. Land at higher elevations has been cleared for small scale agriculture. Loss of the paramo ecosystem will exert a number of negative impacts on ecosystem services and livelihoods of the local population at Pambamarca.展开更多
